Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] See also Figure 1 As shown, the present invention is a method for inspecting and monitoring the operation of photovoltaic power generation equipment based on AIoT, and the method includes the following steps: Step S1: perform an inspection on the photovoltaic power generation equipment at regular intervals, and collect the operating parameters of the photovoltaic power generation equipment in real time during the inspection; Step S2: After receiving the collected data, the edge computing device preprocesses the data, including filtering the sensor data to remove noise interference; denoising and enhancing the image data to improve image quality; and normalizing the data to convert data of different types and ranges into a unified format and range for subsequent analysis.

[0019] Through the above technical solution, the present invention conducts an inspection of photovoltaic power generation equipment at regular intervals in order to timely discover equipment failures and predict failures, thereby improving the operating reliability and power generation efficiency of photovoltaic power generation equipment. Sensor data and image data of the equipment during operation are collected in real time, and the collected data are denoised and enhanced. At the same time, data of different types and ranges are converted into a unified format and range, and then feature extraction is performed on the processed data to obtain the electrical state, physical state and deformation state of the photovoltaic power generation equipment and the photovoltaic panel. Then, the operating state of the photovoltaic power generation equipment is evaluated based on the acquired state information, and the next inspection cycle is adjusted according to the evaluation results.

[0022] Through the above technical solution, this embodiment extracts the characteristics of the current electrical state of the photovoltaic device, obtains the DC side parameters and AC side parameters of the current photovoltaic device respectively, and then calculates the DC side and AC side state coefficients based on the DC side parameters and AC side parameters, and then substitutes them into the mathematical model The electrical state coefficient of photovoltaic power generation equipment is calculated, where: Used to correct non-standard temperatures and simulate the impact of actual working conditions. It is the electrical state per unit light and per unit area, reflecting the energy conversion efficiency of the entire system.

The bracket inclination deviation and component deformation displacement are divided by the reference value set by the system, and then the comparison values ​​are weighted and summed to obtain the mechanical state coefficient of the photovoltaic power generation equipment.

[0024] Construct a mathematical model of the physical state coefficient of photovoltaic equipment, the expression is: ; Where, is the thermodynamic state coefficient, is the mechanical state coefficient, The light intensity reference value set for the system, The reference value of photovoltaic panel area set for the system, and are the thermodynamic and mechanical weight coefficients, and are the thermodynamic and mechanical correction factors, is the physical state coefficient of the photovoltaic equipment.

[0025] Through the above technical solution, this embodiment extracts the characteristics of the current physical state of the photovoltaic device, obtains the thermodynamic parameters and mechanical parameters of the current photovoltaic device, and then calculates the thermodynamic and mechanical state coefficients based on the thermodynamic parameters and mechanical parameters, and then substitutes them into the mathematical model The physical state coefficient of photovoltaic power generation equipment is calculated, where: The light intensity correction term is used to adjust TSC according to actual lighting conditions. When the light intensity is close to the optimal value, the ratio is close to 1. If the light is too strong or insufficient, the effectiveness of TSC will be reduced. The area correction term is used to adjust the PSC according to the actual PV panel area. It reflects the adverse effects that may be caused by too large or too small panel area (such as heat dissipation problems or low cost efficiency).

Therefore, using its reciprocal can intuitively reflect the impact of the degree of curvature on the deformation coefficient. The entire expression is divided by the photovoltaic panel area A to ensure that the deformation coefficient is comparable and not directly affected by the panel size.

[0028] The working process of step S4 includes: Based on the key features of the equipment operating status extracted in step S3, the operating status coefficient of the photovoltaic power generation equipment is constructed, and the expression is: ; Where, 、 Represent the weight coefficients of electrical state, physical state and deformation state respectively, is the operating status coefficient of photovoltaic power generation equipment; The operating status of the equipment is evaluated based on the electrical status, physical status and deformation status coefficient of the photovoltaic equipment and the operating status coefficient of the photovoltaic power generation equipment.

[0029] The working process of evaluating the operating status of the equipment includes: Compare the electrical state, physical state and deformation state coefficient of the photovoltaic device with the corresponding state coefficient thresholds set by the system. If any state coefficient is greater than or equal to the state coefficient threshold set by the system, it means that the photovoltaic device is unqualified in this state; otherwise, it means that the photovoltaic device is qualified in this state. If the electrical state, physical state and deformation state are all qualified, the photovoltaic equipment will compare the photovoltaic power generation equipment operating state coefficient with the photovoltaic power generation equipment operating state coefficient threshold set by the system. When the photovoltaic power generation equipment operating state coefficient is greater than or equal to the threshold set by the system, it means that there is a risk in the overall operating state of the photovoltaic equipment, and the inspection cycle is shortened. When the photovoltaic power generation equipment operating state coefficient is less than the threshold set by the system, it means that there is no risk in the overall operating state of the photovoltaic equipment, and the inspection cycle is increased.

When the photovoltaic power generation equipment operating status coefficient is greater than or equal to the threshold set by the system, it indicates that there is a risk in the overall operating status of the photovoltaic equipment, and the inspection cycle is shortened. When the photovoltaic power generation equipment operating status coefficient is less than the threshold set by the system, it indicates that there is no risk in the overall operating status of the photovoltaic equipment, and the inspection cycle is increased.

[0031] An AIoT-based photovoltaic power generation equipment operation inspection and monitoring system, the system comprising: a data acquisition module, a data processing module, a data analysis module, and a status assessment module; The data acquisition module is used to collect status parameters of photovoltaic power generation equipment; The data processing module is used to filter the sensor data, perform denoising and enhancement processing on the image data, and perform normalization processing on the data; The data analysis module is used to extract features from the pre-processed data to extract key features that can reflect the operating status of the equipment; The status evaluation module is used to evaluate the operating status of the equipment and adjust the inspection cycle according to the evaluation results.
